Re: Dell P2412h LED monitor shows pink tint in white screens

Thanks, Ifixstuff9, I was told by a tv repair guy that it's probably the T-Con board along the bottom of the panel, and not repairable (I tried to separate one once and of course just split the glass open as well) and not worth fooling with for a $45 monitor used. But it may be the LED as well; I had an old Sony clock radio where the LED display got dimmer and dimmer over time until you could only see it a bit at night so they can just wear out. Either way, it seems to be the panel that's the problem. I'll keep watching for a dead one with a good screen or sell the boards out of it I expect. Thanks!

look at the light shining through the translucent parts of the panel back.
or through holes.
normally led backlights look like daylight fluorescents or 6500-8000k.
i had a 24" samsung with the connector broke off the strip that i repaired.
when i tested the strip i notices the color was about 5000k with a noticeable red spike.
but the monitor looked perfect when i reassembled it.
its far more common though to fade to a dim blue.
just fixed some off road led lightbars for a neighbor that were very dim blue after a years use.
cheap noname leds.
at least they were 3535 type and i have a ton of nichia 219 on hand.

i almost forgot.
pull the lvds and power up.
is the screen now white?
or is it pink?
white means the backlight color is ok.

I will try that with the cable pulled as soon as I get a chance.
